Specification of Letters Patent.

Patented May 5, 1914.

Application filed. July 26, 1912. Serial No. 711,678.

To all whom it may concern:

Be it known that I, LOUIS M. BROWN, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain Improvements in Holddown Devices forLasting-Machines, of which the following description, in connection withthe accompanying drawings, is a specification, like reference characterson the drawings indicating like parts in the several figures.

This invention relates to hold-down devices for use in connectlon withlasting maprovided which will provide adequate security and permit thefoot to be conveniently removed and another foot substituted therei forand this invention comprises an advantageous form of connection adaptedfor this purpose.

The several features of the invention will appear from the followingdescription of the illustrated embodiment thereof and will then bepointed out in the claims.

Figure 1 is a perspective view, partly in section, showing the manner ofattaching the hold-down foot to the hold-down arm, the

foot being shown in full lines detached and in dotted lines in itsoperative position;

Fig. 2 is a longitudinal section of the forepart of a shoe showing inside elevation the hold-down foot applied thereto.

In Fig. 1 the character 2 indicates the arm I of a hold-down provided atits outer end with a stud 1- by which one end of the foot 1 member 20 issecured thereto. The opposite end of the member 20 is provided withforwardly directed teeth to engage the insole be- 1 hind the rib asshown in Fig. 2. The foot I 20 is preferably resilient and the stud a bywhich it is attached to the arm 2 has a roughened head 6, which isadapted to engage the innersole when the pressure of foot 20 against theshoe has caused the foot to yield. The stud 4: is flattened on its sidesat 8 and is maintained in fixed position in a hole in the arm 2 by aspring-held pin 10 having a reduced end which is forced outwardly into ahole 12 in the stud. Obviously the stud may be released for removal bypushing back the pin 10 by means of a pointed instrument insertedthrough the hole 12. Upon the stem of the stud 4 is mounted to turn theresilient holding plate l lwhich extends forwardly under and hassupporting engagement at its front and rear ends with the lower face ofthe curved holddown foot member 20. Near its front end the holding plate14: has lips 16 bent up on its opposite edges to form a seat in whichmember 20 is normally confined.

The foot 20 is provided at one end with an open slot 24 ending in anenlarged recess 22 and is assembled upon the end of the holddown arm bypushing the slotted end upon the stud in the direction of the flattenedsides of the stud until the stud rests in the recess 22 when the springfoot 20 may be rotated about the stud. The lips 16 of the plate 1 1 arearranged to rest against opposite sides of the foot 20 and by reason ofthe tapered formation of the foot 20, Fig. 1, it cannot be pulled fromthe stud even when in line with the flattened sides thereof until thelips 16 on the spring plate 1 1 are depressed below the plane of thefoot 20. The spring plate 14, by crowding the foot 20 against thesupporting arm 2, holds the foot frictionally from rotation on the stud4.

For different styles of shoes different holddown feet maybe provided,the construction shown providing means for readily detaching one footand attaching another. To effect this the operator has only to insert apointed instrument between the spring plate 14; and the foot 20 andseparate them sufficiently to disengage the lips 16 from the foot 20 sothat the plate 14 and foot 20 may be swung relatively toeach other aboutthe stud. The foot 20 may then be detached by rotating it into alinementwith the holddown arm and pulling it outwardly in the direction of saidfoot, the flattened sides of the stud then permitting it to pass throughthe slot 24: of the foot 20. Other hold-down feet may be attached to thehold-down arm by reversing the process described for removing the foot.

The use and operation of the described embodiment of the invention maybe readily understood by those skilled in the art without furtherdescription, and it is also apparent that various modifications of thedevice as described may be made without departing from the invention.

' Having described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is 1. In a hold-down forlasting machines, a hold-down foot,asupport therefor, a headed studhaving flattened sides, the said foot having a hole in one end with arelatively narrow open slot leading therefrom to admit the stud whenmoved thereover in the direction of the flattened sides, and means forholding the foot upon the stud.

- 2. A hold-down for lasting machines comprising a foot having a slottedend, a support therefor carrying a stud adapted to enter the slot, and aspring plate underlying the foot and secured to the stud in position toretain the foot in place upon the support.

8. A hold-down for lasting machines comprising a foot having a slot inits end which terminates in an enlarged recess, a holddown support, aflattened stud having a head secured to the support and adapted to enterthe slot and to turn in the enlarged recess, and a spring plateunderlying the foot and securing it to the stud by means of upturnedlips arranged to engage the sides of the foot. 7

4:- In a machine of the class described, a connection comprising an arm2, a springpressed pin 10 mounted therein, a headed stud t havingflattened faces and a hole 12 adapted to be engaged by said pin 10 toprevent rotation of the stud, and a member 20 having a slot 24 to admitthe flattened portion of the stud 4, said slot having an enlargement topermit relative rotation of the stud and member. j

5. In a machine of the class described, a connection comprising a headedstud, a spring plate mounted thereon and having upturned lips, and atapered member having a slot at its larger end adapted to engage thestud and to be held thereon by the engagement of the lips of the springmember upon its opposite tapered sides.

6. A hold-down for shoe lasting machines, comprising supporting andoperating means movable over a shoe located in position to be lasted in,the machine and having a coupling formation, and a plate, having acomplemental coupling formation detachably engageable with the firstmentioned coupling formation, one of said parts being provided with aspring plate secured to it and engaging the other to resist adisengaging movement of the plate from its supporting and operatingmeans.

7 A hold-down for shoe lasting machines comprising a supporting andoperating means movable over a shoe located in position to be lasted inthe machine and having a stud to engage the shoe bottom, a curvedhold-down foot member adapted to engage the toe of the shoe innersoleand having a detachable engagement with said means, a resilient holdingplate mounted to turn on the stud and extending forwardly under andhaving supporting engagement at its front and rear ends with the lowerface of the curved foot member, and lips bent to re strain the front endof the holding plate and the foot member from relative turning movement.

8. In a hold-down for shoe lasting machines, an arm movable to extendtransversely across the shoe, a hold-d own member carried thereon toextend from said arm longitudinally of the shoe toward its toe, and aconnection between said arm and member which is rigid againstdisplacement by upward pressure thereon, comprising a member attachingstud snugly fitting the arm and depending therefrom, and. a locking pinhaving a lower face perpendicular to the at taching stud, spring pressedfrom said arm outwardly and having a reduced cylindrical portion seatingin the attaching stud, the stud and the end portion of the arm havingalined apertures through which access may be had to said reduced portionof the pin for pressing it out of its seat in the stud.

9. In a hold-down for shoe lasting machines an arm movable to extendtransversely across a shoe, a hold-down member carried thereon to extendfrom said arm longitudinally of the shoe toward its toe, and aconnection between said arm and member which is rigid againstdisplacement by downward pressure applied to the shoe toe by saidmember. the connection comprising a member attaching stud having a stemextending upwardly into the arm, a seat in the arm snugly fitting thestem, and a locking pin extending from the arm transversely LOUIS M.BROVN.
